摘要
作为一种电极材料或电极修饰材料,PEDOT:PSS薄膜常用于有机光电器件领域的应用研究。然而,较低的电导率(≤0.8S/cm)与酸性(pH=1.5~2.5)已成为限制PEODT:PSS薄膜在上述领域进一步应用的瓶颈,因此,PEDOT:PSS薄膜性能优化正在成为一个新的研究热点。文中综述了近年来PEDOT:PSS薄膜性能优化研究的新进展,着重论述了有机物掺杂、无机物掺杂、热处理、紫外/臭氧处理、氧等离子体处理以及外加电场等多种方式对PEDOT:PSS薄膜电/光性能的优化效果及相关机理研究。同时,文章对PEDOT:PSS薄膜性能优化研究工作中存在的焦点问题亦进行了客观分析与评价,并探讨了未来研究重点。
As an electrode or electrode modified materials, films fabricated from commercially available poly (3,4-ethylenedioxythiophene) (PEDOT):poly (4-styrenesulfonate) (PSS) aqueous dispersions were widely used in modern organic optoelectronic devices. However, the film also suffers the low conductivity (≤0.8S/cm) and the acidity (pH=1.5~2.5), which are main limiting factors for the practical application. Therefore, the optimization of film properties has attracted a lot of attention. In this review, the new developments in the properties optimization of PEDOT: PSS films were summarized. More attention was paid to the improvement of PEDOT: PSS film properties by some especial treatment, such as organic doping, inorganic doping, thermal treatment, UV-ozone treatment, plasma treatment and high-electric-field treatment. Moreover, the mechanism of the performance optimization for PEDOT: PSS films were also mentioned. Finally, the confused problems and prospects of the research on the optimization of PEDOT: PSS film properties were commented.
